SAFETY-LOCK FOR flRE-ARMS.

ermine-Arron forming part of Letters Patent No. 320,038, dated June16,1885.

Application filed March 24. 1885. (No model.)

ingsfand to the letters and figures of reference marked thereon,'whichform apart of this specification.-

My invention has relation to automatic safety-locksfor fire arms, andthe object is to provide a device for locking the triggers, so as torender the gun inoperative at all times, except when the triggers arereleased by the action of the locking device; and to this end thenovelty consists in the combination, with the main triggers, of asecondary or looking trigger adapted to engage said main triggers andrender them inoperative at all times except when unlocked by the actionof the secondary trigger, as will be hereinafter more fully described. a

r In the accompanying drawings the same letters of reference indicatethe same parts of theinventiou.

. Figure 1 is a side elevation of the stock of adouble-barreledbreech-loading shot-gun embodying my invention. Fig. 2 is asideelevation of thetrigger-plate removed from the gun. Fig. 3 is a top planview of the same, and Fig. 4is a detached view in perspective of thelocking-lever. I

A is the trigger-plate, and B the guard. C

C are the triggers, D is a lever pivoted to a projection, a, on theinside of the triggerpla'te andextending forward so that its freebifurcated ends (1 (1 will come in contact with the eirtensions c c ofthe triggers O G. E is a screw-stud passing through the hole d in l thelever D, and secnredto the trigger-plate Al F is a spiral springextending from under the head of the serewE down to the lever D,

and its object is to press the said'lever downward against thetrigger-plate, which is its normal position. contact with the triggersand prevents their slightest movement. G is a stud secured to andextending downward from the .lever D, passing through a hole in thetrigger-plate and also through one in trigger-guard, terminatingin acurved finger-pieee,H,located outside of the trigger-guard. The spiralspring F in pressing the lever D downward forces triggers and in theline of their motion, so that while the lever is in this position it isimpossible to operate them. If, however, the fingerpiece H be pressedupward the ends d d are 5 This keeps the ends :1 d in. a

its ends (1 d against the extensions 0 c of the raised above and out ofthe path of the trig ger-extensions c c, and of course, there being noobstacle in the way, they may be readily pulled to. fire the gun in theusual manner. The normal position of the lever D being that of a lock tothe triggers, it follows that it is impossible to fire tliegun throughaccidentor carelessness, and it can only be done by first pressing thefinger-piece H upward and then pullingthe trigger. The moment the handis removed from'the piece H the spring F restores the lever D to itsnormal position, which action immediately locks the triggers andeffectually prevents their being operated except asabove stated. .a

- Having'thus described my inv'ention,'whatI claim as new and useful,and desire to secure by Letters Patent of the United States, is-

The combination, with the trigger of a firearm, of the locking-lever 'D,pivoted to the trigger-plate B, and provided with the projecting curvedfinger-piece H and the stud E, secured to the trigger-plate and havingspiral springF adapted to normally hold said lever in contact with andlock the triggers, as and for the purpose set forth.

- In testimony-whereof I afiix my signature in presence of twowitnesses. PETER A. ALTMAIER.
